TSAMP/RSCT will declare the domain Online after IBM.ConfigRM has initialized all nodes, and heartbeating etc is available.

It is only after the domain is Online further subsystems like RecoveryRM and GlResRM are started and initialized.

Hence, even if a domain is online, it does not mean that the subsystems like RecoveryRM are fully started and initialized.

If you have a script to automate certain tasks that require RecoveryRM, it is best to check the state of RecoveryRM using command "lssrc -ls IBM.RecoveryRM | grep -i 'In Config State'". If the returned value is TRUE, then it is safe to say that RecoveryRM is fully started and initialized.
